SLUDGE-TABLE BLOCK.

Be it known that I, FRED DUNHADL, a citizen of the United States, residing at Commerce, in the county of Ottawa and State of Oklahoma, have invented certain new and useful Improvements in Sludge-Table Blocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide means for facilitating the communication of movement to the sludge table from the thrust bar to avoid lost motion and therefore unnecessary arring and straining of the parts of the mechanism, and with this object in view the invention consists in a construction of which a preferred embodiment is shown in the accompanying drawing; wherein Figure 1 is a side view of a thrust table apparatus having the improved thrust block arranged in operative relation therewith.

Figure 2 is a detail section in the plane of the thrust block and showing the related portions of the connection between the deck head of the sludge table and the thrust bar.

Figure 3 is a detail View of the thrust block.

A sludge table of the ordinary construction and of the form commonly employed at present in mines for the cleaning of the ore is indicated at 10, the same being provided with the usual inclined deck head 11 through which extends the draw bar 12, and at 13 is shown a typical thrust bar having a terminal yoke 14 in which is connected the projecting end of the draw bar 12 as a means of communicating motion from the thrust bar to the sludge table. Ordinarily the end of the thrust bar or the yoke carried thereby comes in contact with the deck head during the thrust movement of the bar, and owing to the indicated connect-ion between the parts there is a certain amount'of lost motion Specification of Letters Patent.

which results in subjecting the deck head to continued pounding and jarring which not only results in rapid deterioration of the mechanism but a relative inefiiciency of the apparatus, and to overcome these disadvantages a tapered or wedge shaped block 15 is interposed between the thrust bar and the exterior surface of the deck head, the same having an opening 16 through which the bar extends and by which it is held in proper position with relation to the thrust bar and deck head, to the end that it completely occupies the space between said elements and serves by reason of fiat bearing contacts with both the deck head and the yoke 14 or the end of the thrust bar, to communicate motion directly from one to the other without jar or Vibration.

It will be understood that the device can be introduced and employed in connection with an apparatus which is already in use and may be modified in dimensions to suit the particular apparatus to which it is to be applied.

hat is claimed is The combination with a sludge table having an inclined deck head and a draw bar extending therethrough from a thrust bar to normally directly contact with said deck head, of a block unattached to said head, separable from and mounted on the bar intermediate the deck and thrust bar, having an inclined face to engage the deck head and a face at an angle to said face to e11- gage the thrust bar so as to be self positioning in combination with the thrust bar and draw bar fastening and to overcome lost mo tion and the usual pounding and arring be tween the thrust bar and deck head.

In testimony whereof I aliix my signature in presence of two witnesses.
